摘要
利用Fluent6.3软件,采用k-ε组份输运模型,进行基于海上平台热介质锅炉进行二维数值计算,分析了锅炉燃烧产生的废气在空气中形成的烟羽对操作平台和住人平台的影响.结果表明,当风速较小时,操作平台和住人平台区域温度较高,烟气浓度较大,氧气浓度适宜;当风速较大时,操作平台和住人平台区域温度较低,烟气浓度较小,氧气浓度较小.
The k-epsilon component transport model is applied to proceed two-dimensional numerical calculation for offshore oil platform heat medium boilers with the fluent 6. 3 software. The calculation analyzes the influence of smoke plume formed in the air from boiler combustion on the operation platform and living platform. The numerical results show that when the wind speed is relatively lower,the temperature of operating platform and the occupant platform is higher,the flue gas concentration is larger,and the oxygen concentration is suitable. When the wind speed is relatively higher,the temperature of operating platform and the living platform is lower,the smoke concentration is small,and the oxygen concentration is small and not suitable.
